FIELD OF THE DISCLOSURE

The present disclosure generally relates to drug delivery devices and, more particularly, to enabling a sterile drug container assembled within a drug delivery device.

BACKGROUND

Drug delivery devices, such as injectors, are used to deliver liquid drugs to a patient. Upon activation, a drug delivery device will expel a drug stored within an internal reservoir through a needle, cannula, or other delivery member into the patient. Certain drug delivery devices are manufactured with an empty reservoir, and the patient or healthcare provider (e.g., a doctor, nurse, healthcare assistant, etc.) will fill the reservoir with the drug at the time of use. Typically, this requires the patient or healthcare provider to operate a syringe to inject the drug into the empty reservoir through an inlet port formed in the drug delivery device. Prior to this filling procedure, the inlet port should be sterilized by swabbing its outer surface with an alcohol wipe, for example. Alternatively, certain drug delivery devices are installed with a pre-filled drug container by the patient or healthcare provider at the time of use. Before installing the pre-filled drug container, mating connectors disposed on, respectively, the pre-filled drug container and a fluid pathway assembly within the device should be sterilized, for example, by swabbing them with an alcohol wipe. In either case, the drug delivery device must be prepared by the patient or healthcare provider prior to use.

More recently, drug delivery devices have become available which are pre-assembled with a pre-filled drug container. This alleviates the patient or healthcare provider from having to add the drug to the drug delivery device at the time of treatment. In such drug delivery devices, a sterile fluid flow path is established between the pre-filled drug container and a fluid pathway assembly upon activation of the device. Generally, this involves accessing an interior of the drug container with a container access needle such that the drug can be expelled from the container via the container access needle. Prior to activation of the device, the container access needle should be maintained in a sterile condition so that the container access needle does not introduce contaminants into the container upon activation of the device. In some approaches, existing assemblies for creating a sterile environment for the drug container may be incapable of adequately sterilizing required components and/or desired surfaces. For example, a gaseous sterilizing mixture (such as, for example ethylene oxide and/or saturated steam) may be incapable of adequately penetrating or permeating through components in order to adequately sterilize certain components. In other examples, some existing approaches may also negatively impact the appearance or structural integrity of the container, or alternatively may adversely impact the drug itself. In these examples, a user or healthcare provider may need to visually inspect the device to ensure that there are no potentially hazardous contaminants in the container. In the event that the appearance and/or structural integrity of the container may be compromised, it may be difficult or impossible to conduct visual inspections, and thus, containers may be preemptively unnecessarily disposed of.

The present disclosure sets forth systems and approaches for sterilization of drug delivery devices and related methods of assembly and sterilization embodying advantageous alternatives to existing sterilization systems and methods, and that may address one or more of the challenges or needs mentioned herein, as well as provide other benefits and advantages.

DETAILED DESCRIPTION

The present disclosure generally relates to systems and approaches for sterilizing a container for a drug delivery device. Generally, the container is coupled to a stopper and a crimping device to form a sealed unit and the sealed unit is disposed within a shield member. Electron Beam (referred to as “E-Beam”) Irradiation is applied to the sealed unit to sterilize a contact surface between the container and the stopper which is contained within the crimping device. By advantageously relying on the geometry of the sealed unit and the shield member, suitable irradiation may reach the contact surface for the purpose of providing sterilization, while the shield member, the crimping device, and/or the stopper may act, individually or cooperatively, to limit penetration of the irradiation beams, that is, to avoid exposing the container and drug contacting surfaces to ionizing irradiation that could impact its physical, chemical, or aesthetic attributes. As such, the irradiation is shielded from the remainder of the container, thereby reducing and/or eliminating the potential for discoloration to the container, the drug that may be contained therein, and/or any other components. As a result, a user may properly inspect the contents of the container prior to drug administration, thereby reducing the number of unnecessarily disposed containers.

FIG. 1 is a schematic illustration of one embodiment of a drug delivery device 10 constructed in accordance with principles of the present disclosure. The drug delivery device 10 may be operated to subcutaneously or transdermally deliver a drug to a patient. In the illustrated embodiment, the drug delivery device 10 is configured as a wearable drug delivery device, such as an on-body injector or an ambulatory infusion pump, and is releasably attachable to the patient's tissue 11 (e.g., the patient's skin). In other embodiments (not illustrated), the drug delivery device 10 may be configured as a pen-type injector, such as an autoinjector or injection pen, which is temporarily held against the patient's tissue 11 over the course of the injection. The drug delivery device 10 may be configured to automatically deliver a fixed or a patient/operator-settable dose of the drug over a controlled or selected period of time. Furthermore, the drug delivery device 10 may be intended for self-administration by the patient, or may be operated by a formally trained healthcare professional or other caregiver to administer the injection.

Generally, the drug delivery device 10 may include an insertion mechanism 12, a container assembly 14 including a container 15, a fluid pathway assembly 22, a drive mechanism 24, and a controller 26, each of which may be disposed within an interior space of a main body 29. An actuator 28 (e.g., a user-depressible button, touchscreen, microphone, etc.) may protrude through or otherwise be disposed at an exterior surface of the body 29 and may be configured to initiate operation of the drug delivery device 10 by activating, via mechanical and/or electrical means (shown in dotted lines in FIG. 1), the insertion mechanism 12, the fluid pathway assembly 22, the drive mechanism 24, the controller 26, and/or other mechanisms and/or electronics. In embodiments where the actuator 28 is a button that is depressed or otherwise physically moved by a user or patient, the actuator 28 may be configured to exert a motive force needed to activate the insertion mechanism 12, the fluid pathway assembly 22, the drive assembly 24, the controller 26, and/or other mechanisms. In such embodiments, the actuator 28 may be physically connected to, either directly or indirectly via a mechanical linkage, the insertion mechanism 12, the drive mechanism 24, the fluid pathway assembly 22, and/or other mechanisms such that manually depressing or otherwise interacting with the actuator 28 supplies the motive force necessary to activate the insertion mechanism 12, the drive mechanism 24, the fluid pathway assembly 22, and/or other mechanisms. For example, in some embodiments, manually depressing the actuator 28 may cause the fluid pathway assembly 22 to move towards the stationary container assembly 14, or cause the container assembly 14 to move towards the stationary fluid pathway assembly 22, and thereby cause a container access needle to penetrate through a seal member into a reservoir or interior volume of the container assembly 14. Additionally or alternatively, the actuator 28 may operate as an input device that transmits an electrical and/or mechanical signal to the controller 26, which in turn may execute programmable instructions to control operation of the insertion mechanism 12, the drive mechanism 24, the fluid pathway assembly 22, and/or other mechanisms. In such embodiments, the controller 26 may include a processor (e.g., a microprocessor) and a non-transitory memory for storing the programmable instructions to be executed by the processor. Furthermore, in such embodiments, the drug delivery device 10 may include an internal actuator (e.g., an electric motor, a pneumatic or hydraulic pump, and/or a source of pressurized gas or liquid) which is separate from the actuator 28 and which, in response to an electrical control signal received from the controller 26, exerts the motive force needed to activate the insertion mechanism 12, the drive mechanism 24, the fluid pathway assembly 22, and/or other mechanisms.

The body 29 may include a bottom wall 25 configured to be releasably attached (e.g., adhered with an adhesive) to the patient's tissue 11, and a top wall 27 including one or more visual indicators 42 (e.g., lights, graphical displays, etc.) and/or a window 35 for viewing the container 15 and a drug 32 contained therein. The one or more visual indicators 42 may be used to communicate information to the user about the operational state of the drug delivery device 10 and/or the condition of the drug 32. An opening 31 may be formed in the bottom wall 25, and optionally a pierceable sterile barrier 33, such as a pierceable septum, may extend across the opening 31 to seal the interior of the body 29 prior to use. In some embodiments, the pierceable sterile barrier 33 may be omitted, and instead a removable sealing member (not illustrated) may cover and seal close the opening 31 prior to use.

More particularly with respect to the window 35, this element may be constructed of a transparent or semi-transparent material and generally aligned with the container 15, so as to allow a patient or user of the drug delivery device 10 to inspect the drug 32 within the container 15 and/or confirm dose completion. Suitable materials for constructing the window 35 include, but are not limited to, glass and/or plastic. The location of the window 35 on the exterior of the drug delivery device 10 may expose the drug 32 to ambient light including sunlight. Some drugs may be sensitive to certain wavelengths of light and undergo undesirable molecular changes when exposed to such wavelengths of light. For example, some drugs may be sensitive to wavelengths of light in the ultraviolet (UV) range, the visible range, and/or the infrared range. To protect drugs that are primarily sensitive to light in the UV range and/or the infrared range, a dark tint may be added to the window 35 and/or the window 35 may be dimensioned to cover a relatively small surface area of the body 29. For drugs that are primarily sensitive to light in the visible range, it may not be necessary to add a dark tint to the window 35 and/or shrink the size of the window 35. Instead, the window 35 may be constructed with a polarized filter. In some embodiments, the polarized filter may be a film or other coating that is applied to the window 35. In other embodiments, the polarized filter may be integrated directly into the material of window 35. The polarized filter may allow for viewing and inspection of the drug 32 within the container 15, while filtering out up to and including approximately (e.g., ±10%) 50% of light in the visible range. In some embodiments, the portion of visible light filtered out by the window 35 may fall in a range between approximately (e.g., ±10%) 0-50%, or 10-50%, or 20-50%, or 25-50%, or 0-40%, or 0-30%, or 0-25%, depending on the photosensitivity of the drug 32 and/or the eye strength of the patient population of the drug 32, among other considerations. Adding the polarized filter to the window 35, in lieu adding a dark tint to the window 35 and/or shrinking the size of the window 35, advantageously protects the drug 35 from light in the visible range without substantially compromising the ability of the patient or user of the drug delivery device 10 to inspect the drug 32 within the container 15.

After the bottom wall 25 of the body 29 is attached to the patient's tissue 13, the insertion mechanism 12 may be activated to move a delivery member from a retracted position within the body 29 to a deployed position extending outside of the body 29. In the present embodiment, this may include the insertion mechanism 12 inserting a trocar 21 and a hollow cannula 23 surrounding the trocar 21 through the pierceable sterile barrier 33 and into the patient's tissue 11, as illustrated in FIG. 1. Immediately or shortly thereafter, the insertion mechanism 12 may automatically retract the trocar 21, leaving the distal open end of the cannula 23 inside the patient for subcutaneous delivery of the drug 32. The trocar 21 may be solid and have a sharpened end for piercing the patient's skin 11. Furthermore, the trocar 21 may be made of a material that is more rigid than the cannula 23. In some embodiments, the trocar 21 may be made of metal, whereas the cannula 23 may be made of plastic or another polymer. The relative flexibility of the cannula 23 may allow it to be disposed subcutaneously within the patient's tissue 11 for a period of a time without causing pain or significant discomfort to the patient. In other embodiments (not illustrated), the trocar 21 and cannula 23 may be omitted, and instead the insertion mechanism 12 may insert only a rigid, hollow needle into the patient for subcutaneous delivery of the drug 32.

In some embodiments, the insertion mechanism 12 may include one or more springs (e.g., coil springs, torsion springs, etc.) initially retained in an energized state, and which are released upon depression of the actuator 28 in order to insert the trocar 21 and cannula 23, or hollow needle, into the patient. Furthermore, retraction of the trocar 21 may be achieved by the automatic release of another spring after the trocar 21 and cannula 23 have been inserted into the patient. Other power sources for insertion and/or retraction are possible, including, for example, an electric motor, a hydraulic or pneumatic pump, or a canister that releases a pressurized gas or pressurized liquid to provide actuation energy.

With reference to FIGS. 1-2C, the container assembly 14 includes a container 15, which in some contexts may be referred to as a primary container, a seal member 40, and a coupling device 91. The container assembly 14 may include a proximal or first end 36 and a distal or second end 37 at which the seal member 40 and the coupling device 91 are positioned. The container 15 has an elongated portion or wall 38 extending between the first end 36 and the second end 37. The wall 38 has an interior surface 43 defining an inner volume or reservoir 30 that is filled with the drug 32 and further may have an exterior surface 47. In some embodiments, the reservoir 30 may be pre-filled with the drug 32 by a drug manufacturer prior to installation of the container 15 in the drug delivery device 10. In some embodiments, the container 15 may be rigidly connected to the body 29 such that the container 15 cannot move relative to the housing; whereas, in other embodiments, the container 15 may be slidably connected to the body 29 such that the container 15 can move relative to the body 29 during operation of the drug delivery device 10. The container 15 may have an elongate, barrel-like or cylindrical shape extending along a longitudinal axis A. In embodiments where the drug delivery device 10 is configured as an on-body injector, the longitudinal axis A of the container 15 may be perpendicular or substantially perpendicular, or otherwise non-parallel, to a direction in which the insertion mechanism 12 inserts a delivery member such as the cannula 23 into the patient. This configuration may allow the on-body injector to have a generally planar, low-profile shape that can be worn by the patient without impeding the patient's movement. Initially, a stopper 34 or other piston member may be positioned in the reservoir 30 at the proximal or first end 36 of the container 15. The stopper 34 may sealingly and slidably engage the interior surface 43 of the wall 38 of the container 15, and may be movable relative to the wall 38 of the container 15.

The volume of the drug 32 contained in the reservoir 30 prior to delivery may be: any volume in a range between approximately (e.g., ±10%) 0.5-20 mL, or any volume in a range between approximately (e.g., ±10%) 0.5-10 mL, or any volume in a range between approximately (e.g., ±10%) 1-10 mL, or any volume in a range between approximately (e.g., ±10%) 1-8 mL, or any volume in a range between approximately (e.g., ±10%) 1-5 mL, or any volume in a range between approximately (e.g., ±10%) 1-3.5 mL, or any volume in a range between approximately (e.g., ±10%) 1-3 mL, or any volume in a range between approximately (e.g., ±10%) 1-2.5 mL, or any volume in a range between approximately (e.g., ±10%) 1-2 mL, or any volume equal to or less than approximately (e.g., ±10%) 4 mL, or any volume equal to or less than approximately (e.g., ±10%) 3.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 3 mL, or any volume equal to or less than approximately (e.g., ±10%) 2.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 2 mL, or any volume equal to or less than approximately (e.g., ±10%) 1.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 1 mL. The reservoir 30 may be completely or partially filled with the drug 32. The drug 32 may be one or more of the drugs described below, such as, for example, a granulocyte colony-stimulating factor (G-CSF), a PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) specific antibody, a sclerostin antibody, or a calcitonin gene-related peptide (CGRP) antibody.

During operation of the drug delivery device 10, the drive mechanism 24 may push the stopper 34 along the longitudinal axis A from the proximal end 36 of the container 15 to the distal end 37 of the container 15 in order to expel the drug 32 from the container 15. In some embodiments, the drive mechanism 24 may include one or more springs (e.g., coil springs, torsion springs, etc.) initially retained in an energized state, and which are released upon depression of the actuator 28. Following their release, the spring(s) may expand or contract to move the stopper 34 through the reservoir 30 along the longitudinal axis A from the proximal end 36 of the container 15 to the distal end 37 of the container 15. In other embodiments, the drive mechanism 24 may include an electric motor (not illustrated) which rotates a gear mechanism, including for example one or more sprocket gears, to cause axial motion of the stopper 34 through the reservoir 30. In still further embodiments, the drive mechanism 24 may include both an electric motor and spring(s), wherein the electric motor regulates expansion of the spring(s) via a tether or pulley system. In still further embodiments, the drive mechanism 24 may include a canister that releases a pressurized gas or pressurized liquid to provide actuation energy.

At the distal end 37 of the container 15, an opening 45 (see FIG. 2A) may be formed in a container contact region or distal end surface 72 (see FIG. 2A) of the wall 38. The container contact region 72 may define a portion of the exterior surface 47 of the wall 38. At least prior to operation of the drug delivery device 10, the opening 45 may be covered and sealed closed by the seal member 40, such as a pierceable septum, connected to the distal end 37 of the container 15. The seal member 40 may include a proximal end surface 73, a seal member contact region 74, and a distal end surface 75. The proximal end surface 73 of the seal member 40 and the interior surface 43 of the wall 38 of the container 15 may define the reservoir 30. Additionally, in some embodiments, a distal end surface 39 of the stopper 34 may define the reservoir 30.

Generally, the seal member 40 may be configured to selectively permit access to the reservoir 30. During operation, the seal member 40 may be physically altered (e.g., pierced) to permit access to and fluid communication with the drug 32 in the reservoir 30. In some embodiments, the seal member 40 may be constructed of a flexible or elastically deformable material such as rubber, for example, which is capable of being penetrated or pierced by a sharpened end or point 63 of a container access needle 60 of the fluid pathway assembly 22. In some embodiments, the seal member 40 may be clamped or otherwise secured to the container contact region 72 of the wall 38 by the coupling device 91 (see FIG. 2B-FIG. 4) and/or adhered directly to the container contact region 72.

Referring back to FIG. 1, fluid pathway assembly 22 may be configured to establish fluid communication between the container 15 and the insertion mechanism 12 via a sterile fluid flow path during operation of the drug delivery device 10. Prior to use of the drug delivery device 10, the fluid pathway assembly 22 may not be in fluid communication with the container 15. During setup of the drug delivery device 10, or during the initial stages of operation of the drug delivery device 10 prior to drug delivery, the user may manually, or the drug delivery device 10 may automatically, enable, connect, or open the necessary connections to establish fluid communication between the container 15 and the fluid pathway assembly 22. Subsequently, the drive mechanism 24 may move the stopper 34 in the distal direction to force the drug 32 stored in the container 15 through the sterile fluid flow path of the fluid pathway assembly 22 and into the cannula 23 or needle or other delivery member of the insertion mechanism 12 for subcutaneous delivery to the patient.

In some embodiments, the fluid pathway assembly 22 may be rigidly connected to the body 29 of the drug delivery device 10 such that the fluid pathway assembly 22 cannot move relative to the housing; whereas, in other embodiments, the fluid pathway assembly 22 may be slidably or moveably connected to the body 29 such that the fluid pathway assembly 22 can move relative to the body 29 during operation of the drug delivery device 10. In the former embodiments, the container 15 may be slidably or moveably connected to the body 29 such that the seal member 40 can be moved toward and pierced by the point 63 of the stationarily arranged container access needle 60 of the fluid pathway assembly 22. In the latter embodiments, the container 15 may be stationarily positioned while the fluid pathway assembly 22 is moved toward the container 15, causing the point 63 of the container access needle 60 to pierce through the seal member 40 and access the reservoir 30.

The fluid pathway assembly 22 may include a first end 44 connected to the container 15, a second end 48 connected to the insertion mechanism 12, and a fluid passage 50 extending between the first end 44 and the second end 48. As described in more detail below, in some embodiments the first end 44 of the fluid pathway assembly 22 may be connected to the container 15 via a clip member 53. The fluid passage 50 may be sterilized, and may be partially or entirely made of a flexible tubing 52. Initially, there may be slack in the flexible tubing 52 to allow the fluid pathway assembly 22 to move relative to the body 29 and/or to allow components of the insertion mechanism 12 to which the fluid pathway assembly 22 is attached to move relative to the body 29. In some embodiments, the fluid passage 50 may include a rigid fluid restrictor element (not illustrated) in addition to the flexible tubing 52. The fluid restrictor element may have a smaller inner diameter than that of the flexible tubing 52 in order to regulate the flow rate of the drug 32 as it passes through the fluid pathway assembly 22. Furthermore, the fluid restrictor element may be made of a more rigid material than the flexible tubing 52. For example, the fluid restrictor element may be made of metal, whereas the flexible tubing 52 may be made of a polymeric material such as plastic.

Still referring to FIG. 1, the first end 44 of the fluid pathway assembly 22 may include the container access needle 60 and an overmold member 62. In general, the overmold member 62 may serve as a mounting member or connection hub for the container access needle 60 and provide a portion of the container access needle 60 which does not access the reservoir 30 with an enlarged outer dimension, such as an enlarged outer diameter. The container access needle 60 may have a sharpened end or point 63, corresponding to a proximal end of the container access needle 60, and a distal end 64 in fluid communication with the fluid passage 50. In the illustrated embodiment, the container access needle 60 has a bend such that the point 63 of the container access needle 60 may be axially aligned with the longitudinal axis A of the container 15 whereas the distal end 64 of the container access needle 60 may be perpendicular or otherwise non-parallel to the longitudinal axis A of the container 15. The overmold member 62 may cover a length of the container access needle 60, including the bend, with the point 63 of the container access needle 60 protruding outwardly from a proximal end 65 of the overmold member 62. As shown in FIG. 1, a distal end 66 of the overmold member 62 may include a mouth or opening that allows an end of the flexible tubing 52 to be inserted into the overmold member 62. In alternative embodiments, the distal end 66 of the overmold member 62 may be inserted into an opening formed in the end of the flexible tubing 52.

The container access needle 60 may possess a hollow, tubular shape with one or more openings at each of the point 63 and the distal end 64. The container access needle 60 made be constructed of a rigid material including, but not limited to, metal (e.g., stainless steel) and/or plastic. In some embodiments, the overmold member 62 may be constructed of a different material than the container access needle 60 such that the overmold member 62 and the container access needle 60 are separate, but rigidly connected components. In some embodiments, the overmold member 62 may be constructed of a rigid plastic material whereas the container access needle 60 is constructed of metal. In other embodiments, the overmold member 62 and the container access needle 60 may be made of the same material such that they form a single, unitary one-piece structure.

Generally, the overmold member 62 may have a sleeve-like or tubular shape that surrounds a length of the container access needle 60. The overmold member 62 may be fixedly or rigidly connected to the needle 60 such that the overmold member 62 and the needle 60 can move together jointly as a single unit or structure. Stated another way, the overmold member 62 may be fixedly or rigidly connected to the container access needle 60 such that the needle 60 is prevented from moving relative to the overmold member 62. In some embodiments, the fixed or rigid connection between the overmold member 62 and the container access needle 60 may be achieved by having the material of the overmold member 62 bond to the material of the container access needle 60. Such bonding may be achieved by forming the overmold member 62 around the container access needle 60 by way of an overmolding or insert molding process. In some such embodiments, the container access needle 60 may be placed in a mold and subsequently a melted plastic, or other melted material, may be poured or injected into the mold and allowed to solidify to form the overmold member 62. Other processes for manufacturing the overmold member 62 are possible as well. In alternative embodiments, the overmold member 62 may be formed with a through hole or passage extending between the proximal and distal ends 65 and 66 and subsequently the container access needle 60 may be inserted into this through hole or passage. In such embodiments, the container access needle 60 may be secured to the overmold member 62 via, for example, an interference-fit connection, an adhesive, and/or a fastener.

At least the proximal end 65 of the overmold member 62 may flushly cover a length of the container access needle 60 with no gaps therebetween. As seen in FIG. 1, there may be a gap between the distal end 66 of the overmold member 62 and the container access needle 60 to form the mouth or opening for receiving the flexible tubing 52. In alternative embodiments, no mouth or opening may be formed in the distal end 66 of the overmold member 62 such that the no gap exists between the distal end 66 of the overmold member 62 and the container access needle 60.

As shown in FIG. 1, and described below in more detail with reference to FIGS. 2A-2C, prior to activation of the drug delivery device 10 (e.g., in a storage state), the overmold member 62 may define an enclosed clean space 68 between the overmold member 62 and the seal member 40. In some embodiments, the enclosed clean space 68 may be an empty space which has been sterilized and which may or may not be a vacuum. In other embodiments, the enclosed clean space may be a space filled with a gaseous or liquid sterilizing agent. In the embodiment illustrated in FIGS. 1-2C, a boundary (e.g., a sterile boundary) of the enclosed clean space 68 may be defined solely by an exterior surface 77 of the overmold member 62 and an interior surface 79 of the seal member 40. However, the boundary of the enclosed clean space 68 may not to be limited to surfaces of overmold member 62 and the seal member 40. In some embodiments, an O-ring (not illustrated) may be disposed around the proximal end 65 of the overmold member 62 such that the boundary of the enclosed clean space 68 is defined by an exterior surface of the O-ring in addition to the exterior surface 77 of the overmold member 62 and the interior surface 79 of the seal member 40. In still further embodiments, the boundary of the enclosed clean space 68 may be defined by an interior surface of the clip member 53, an O-ring disposed around the proximal end 65 of the overmold member 62, and the distal end surface 75 of the seal member 40. Other configurations are also possible for defining the boundary of the enclosed clean space 68.

As shown in FIGS. 1 and 2B, prior to activation of the drug delivery device 10, the container access needle 60 may be arranged in a storage position with its point 63 disposed exterior to the reservoir 30. In some embodiments, in the storage position, the point 63 of the container access needle 60 may be disposed in the enclosed clean space 68, thereby inhibiting or preventing contamination of the point 63 of the container access needle 60. In other embodiments, in the storage position, the point 63 of the container access needle 60 may be disposed partially through the seal member 40 such that the point 63 is embedded within the material of the seal member 40. Embedding the point 63 within the material of the seal member 40 may inhibit or prevent contamination of the point 63. In some embodiments, the enclosed clean space 68 may be filled with a gaseous or liquid sterilizing agent, such that during manufacturing, when the point 63 is inserted through the enclosed clean space 68, the point 63 is sterilized by the gaseous or liquid sterilizing agent.

In order to restrain the container access needle 60 in the storage position prior to activation of the drug delivery device 10, the clip member 53 may frictionally engage the exterior surface 77 of the overmold member 62. Accordingly, the clip member 53 may resist movement of the overmold member 62 in a direction toward and/or away from the seal member 40.

As illustrated in FIG. 2C, upon activation of the drug delivery device 10, the container access needle 60 may be moved from the storage position to a delivery position, where the point 63 is disposed through the proximal end surface 73 of the seal member 40 and into the reservoir 30, thereby establishing fluid communication with the reservoir 30 optionally containing the drug 32. In some embodiments, the actuator 28 may be mechanically linked or connected, directly or indirectly, to the container access needle 60 such that manual depression of the actuator 28 provides the motive force necessary for moving the container access needle 60 from the storage position to the delivery position 62. In other embodiments, as described above, an energized actuator (including, e.g., an electric motor, a pneumatic or hydraulic pump, and/or a source of pressurized gas or liquid) may be activated in response to a user's depression of the actuator 28 and provide the motive force necessary for moving the container access needle 60 from the storage position to the delivery position.

Where appropriate, any of the above-described sub-assemblies, mechanisms, components, features, functionalities, methods of manufacture, methods of use, and other aspects of the drug delivery device 10 may be replaced with and/or combined with any of the sub-assemblies, mechanisms, components, features, functionalities, methods of manufacture, methods of use, and other aspects of the drug delivery devices described in some or all of the following documents, each of which is hereby incorporated by reference in its entirety for all purposes: U.S. Pat.

Turning to FIGS. 2A-2C, illustrated is an enlarged view of the container 15, the seal member 40, and part of the fluid pathway assembly 22 of the drug delivery device 10 shown in FIG. 1. The container 15 may have a generally cylindrical shape with a barrel portion occupying most of the proximal end 36, and a neck portion at its distal end 37. In the depicted version, an inner diameter D1 of the distal end 37 neck portion is smaller than an inner diameter of the barrel portion. At the distal end 37 neck portion of the container 15, the wall 38 may protrude radially outwardly to define a container flange 70. The container flange 70 and the wall 38 may be connected via a curved and/or angled shoulder 76. The container flange 70 may extend partially or entirely around a circumference of the distal end 37 of the container 15. The container flange 70 may define a container contact region 72 of the container 15, which is perpendicular or otherwise non-parallel to the longitudinal axis A of the container 15 and generally faces in a distal direction. The opening 45 may be formed in the container contact region 72 and communicate with the reservoir 30 of the container 15. In some embodiments, the container flange 70 may be omitted such that the container contact region 72 does not project radially outwardly of a remainder of the container 15. The wall 38 at the proximal end 36 of the container 15 may include a proximal end surface 89, which is perpendicular or otherwise non-parallel to the longitudinal axis A of the container 15 and generally faces in a proximal direction. An opening 99 may be formed in the proximal end surface 89 and communicate with the reservoir 30. The stopper 34 may inserted through the opening 99 into the container 15. The container 15 may be constructed of glass, a polymeric material such as plastic, or any other suitably inert material which is not likely to chemically interact with the drug 32.

Referring to FIG. 2A, the seal member 40 may be centrally aligned with the longitudinal axis A of the container 15 when the seal member 40 is inserted into the container 15 such that the seal member 40 and the container 15 share the same longitudinal axis A. The seal member 40 may be divided by an imaginary plane perpendicular to the longitudinal axis A into a proximal (or bottom) end 80 and a distal (or top) end 82. The proximal end 81 and the distal end 83 may each possess a generally cylindrical shape and have outer diameters D2 and D3, respectively, as seen in FIG. 2A. The distal end 83 may be enlarged relative to the proximal end 81, such that the outer diameter D3 (or other outer dimension) of the distal end 83 is larger than an outer diameter D2 (or other outer dimension) of the proximal end 81. A flange 84 of the seal member 40 is defined by an outer peripheral (e.g., circumferential) portion of the distal end 83 of the seal member 40 that is disposed radially outwardly of the proximal end 81 of the seal member 40. The seal member contact region 74 is at least partially formed by the flange 84.

Referring to FIGS. 2B, 2C, and 4, when the seal member 40 is attached to the container 15, the proximal end 81 of the seal member 40 may be inserted through the opening 45 into the reservoir 30 and the seal member contact region 74 may directly contact and sealingly engage the container contact region 72 of the container 15 to form a sealing interface 72 a. As illustrated in FIG. 4, the seal member contact region 74 may include an angled portion 74 a that may compress to help form a fluid and/or airtight seal with the container contact region 72.

In some embodiments, the proximal end 81 of the seal member 40 may include one or more radially outwardly protruding annular ribs 100 for sealingly engaging the inner surface 43 of the wall 38 of the container 15. The annular rib(s) 100 may provide a secondary barrier to prevent the ingress contaminants that breach the seal between the flange 84 of the seal member 40 and the container contact region 72 of the container 70. In embodiments including the annular rib(s) 100, the outer diameter D2 of the proximal end 81 of the seal member 40 may be equal to or less than inner diameter D1 of the container 15 while the rib(s) 100 can be slightly larger than D1 in diameter such that the rib(s) 100 compress upon assembly to ensure a tight seal. In other embodiments, the annular rib(s) 100 may be omitted (see FIGS. 3A and 3B), and the outer diameter D2 of the proximal end 81 of the seal member 40 may be slightly larger than the inner diameter D1 of the container 15 to provide a tight fit and seal. In still further embodiments, the annular ribs 100 may be omitted and the outer diameter D2 of the proximal end 81 of the seal member 40 may be smaller than the inner diameter D1 of the container 15, such that there is no seal formed therebetween.

Referring back to FIG. 2A, a depression or recess 80 may be formed in the seal member 40 and dimensioned to receive the proximal end 65 of the overmold member 62. The recess 80 may start at the distal end surface 75 of the seal member 40 and extend into the seal member 40 to a position which is located in the distal direction relative to the proximal end surface 73 of the seal member 40. Accordingly, the recess 80 may define a blind bore having a depth X1. The recess 80 may be defined by an interior surface 79 of the seal member 40. In some embodiments, the recess 79 may receive the overmold member 62 via an interference-fit connection (also referred to as a press-fit connection), such that the interior surface 79 of the seal member 40 sealingly engages an exterior surface 77 of the overmold member 62 to prevent or inhibit the ingress of microbes and other contaminants. The interference-fit connection may be achieved by constructing the proximal end 65 of the overmold member 62 with an outer diameter D4 (or other outer dimension) that is larger than or equal to the inner diameter D5 (or other inner dimension) of the recess 80. The interference-fit connection may result in friction between the interior surface 79 of the seal member 40 and the exterior surface 77 of the overmold member 62 that resists movement of the overmold member 62 relative to the seal member 40. In other embodiments, the outer diameter D4 of the proximal end 65 of the overmold member 62 may be smaller than the inner diameter D5 of the recess 80, and an O-ring (not illustrated) may be disposed around the proximal end 65 of the overmold member 62 to sealingly engage the interior surface 79 of the seal member 40 to prevent or inhibit the ingress of contaminants.

Referring to FIG. 2B, the enclosed clean space 68 may be formed by inserting the proximal end 65 of the overmold member 62 partially into the recess 80, such that the proximal end 65 of the overmold member 62 does not extend the entire depth X1 into the recess 80. The resulting gap between the proximal end 65 of the overmold member 62 and the bottom of the recess 80 may correspond to the enclosed clean space 68. In this way, the enclosed clean space 68 may be defined within the recess 80.

FIG. 2B illustrates that at least a portion of the recess 80 may be disposed in a proximal direction relative to the container contact region 72 of the container 15. Accordingly, at least a portion of the recess 80 may be disposed within the container 15. Thus, when inserted into the recess 80, at least a portion of the overmold member 62 may also be disposed within the container 15. This may reduce an axial length of the overmold member 62 which is disposed exterior to the container 15, which in turn may save space within the body 29 of the drug delivery device 10. As a result, the drug delivery device 10 may be permitted to have a more compact design.

The configuration shown in FIG. 2B corresponds to a storage position or state of the container access needle 60 and the overmold member 62. The overmold member 62 may be held statically in the storage position for a period of time between the completion of assembly of the drug delivery device 10 and activation of the drug delivery device 10 by a user or patient. As shown in FIG. 2B, in the storage position, the point 63 of the container access needle 60 may be disposed in the enclosed clean space 68 and thus exterior to the reservoir 30. In other embodiments, when arranged in the storage position, the point 63 of the container access needle 60 may be disposed partially through the seal member 40 such that the point 63 is embedded within the material of the seal member 40 but nonetheless disposed exterior to the reservoir 30, as described above.

In order to prevent the tip 63 of the container access needle 60 from prematurely piercing through the seal member 40 into the reservoir 30, the clip member 53 may frictionally engage the exterior surface 77 of the overmold member 62. In some embodiments, this may be accomplished by constructing the clip member 53 with a gripping element 90 (see FIG. 2A) that is received in a corresponding groove 92 (see FIG. 2A) formed in the exterior surface 77 of the overmold member 62 in the storage state, as shown in FIG. 2B. Friction between the gripping element 90 and the groove 92 may advantageously resist movement of the overmold member 62, and thus the container access needle 60, toward and/or away from the seal member 40 prior to use of the drug delivery device 10. Upon activation of the drug delivery device 10, an actuator (e.g., the actuator 28 or an internal energized actuator) may be configured to exert a motive force overcoming the frictional force between the gripping element 90 and the groove 92, and also any frictional force between the overmold member 62 and the interior surface 79 of the seal member 40 if an interference-fit connection exists therebetween, to cause the gripping element 90 to slide out of the groove 92 and move the overmold member 62 from the storage position (FIG. 2B) to the delivery position (FIG. 2C). As a result, the point 63 of the container access needle 60 may pierce through the proximal end surface 73 of the seal member 40 into the reservoir 30, thereby establishing fluid communication with the drug 32.

In the present embodiment, the gripping element 90 may be configured as a continuous annular ridge or protrusion. In other embodiments, multiple, distinct gripping elements may be formed on the clip member 53, each of which may be received in a corresponding groove formed in the exterior surface 77 of the overmold member 62 in the storage state.

Referring back to FIG. 2A, the clip member 53 may have an interior surface 94 defining a through hole 95. The through hole 95 may extend between a proximal end surface 96 and a distal end surface 97 of the clip member 53. The proximal end surface 96 of the clip member 53 may be disposed in direct contact with the distal end surface 75 of the seal member 40. The overmold member 62 may extend entirely through the through hole 95 when assembled to the clip member 53, as illustrated in FIGS. 2B and 2C. The gripping element 90 may be disposed on or formed by the interior surface 94, such that the gripping element 90 extends radially inwardly into the through hole 95.

As illustrated in FIGS. 2B and 2C, the coupling device 91 may be configured to hold or clamp the clip member 53 to the container 15, with the seal member 40 positioned between clip member 53 and the container 15. In some embodiments, the coupling device 91 may take the form of a crimp ring that is applied to the container 15 and clip member 53 with a crimping tool. The coupling device 91 may further be adapted to apply a force against the seal member 40 that causes it to compress towards the second end 37 of the container 15. As shown in FIGS. 2B and 2C, the coupling device 91 may include radially inwardly extending flanges 93 a and 93 b that abut against, respectively, a proximally facing surface of the container flange 70 (or other exterior surface of the wall 38 of the container 15) and the distal end surface 97 of the clip member 53, in order to clamp or press the seal member contact region 74 of the flange 84 of the seal member 40 tightly against the container contact region 72 of the container 70. The clamping force provided by the fastener 94 may help ensure an air-tight and/or fluid-tight seal at the sealing interface 72 a between the seal member contact region 74 and the container contact region 72.

Upon assembling the container assembly 14, the arrangement may be subjected to electron beam irradiation to sterilize any residual contaminants trapped within the clean space 68 and/or the sealing interface 72 a. As illustrated in FIGS. 4-6, an electron beam generator 105 can be positioned above the container assembly 14 to generate a sterilizing beam 106 to penetrate any or all of the seal member 40, the coupling device 91, the overmold member 62, the clip member 53, and the sealing interface 72 a (formed by the seal member contact region 74 and the container contact region 72).

In order to effectively sterilize the second end 37 of the container assembly 14, it is necessary to determine an appropriate electron energy level that will maximize penetration (or dosage) of the sterilizing beam 106 at the sealing interface 72 a while approaching zero penetration for the remainder of the elongated portion or wall 38 of the container 15 to ensure the container 15 does not discolor (which would prevent inspection) or otherwise chemically react in a way that may affect drug interaction or mechanical properties of the container 15. Based on desired dimensions of the particular container assembly 14, electron beams may be used having any energy level between approximately 0.3 MeV and approximately 5.0 MeV, or any energy level between approximately 0.5 MeV and approximately 3 MeV, or any energy level between approximately 1 MeV and approximately 2 MeV, or any energy level between approximately 1.1 MeV and approximately 1.7 MeV, or any energy level equal to approximately 1.5 MeV. These energy levels may result in a consistent dose to achieve the desired sterility assurance level (SAL) or could simply be to achieve a disinfection or other desired level of bioburden reduction. Each aim, especially in conjunction with the typical bioburden levels of the particular product, would result in a specific desirable goal dose that could be anywhere from approximately 5 to approximately 50 kGy, and in one version approximately 25 kGy, across the flange site 70 or sealing interface 72 a. The goal dose may be achieved through a single exposure, as discussed, or it may be achieved in multiple lower exposures separated in time that cumulatively add up to the goal dose. For example, in some versions, even multiple sub-5 kGy doses could be applied over time to ultimately achieve the desired goal dose. Other examples are possible. In some approaches, some components of the container assembly 14 may be subject to prior sterilization processes as desired. In order to achieve the desired Sterility Assurance Level (SAL) with a high reliability and confidence in accordance with current good manufacturing practices, in-situ dosimetry within the container assembly 14 may be required during development, initial validation, and routine process validation. One such dosimetry technique would be to use commercially available NIST-traceable polymer dosimetry film. The film would be cut to a custom geometry that would permit it to be placed into interface 72 a during the assembly of container assembly 14 in a manner that does not materially affect the position and orientation of any other components in container assembly 14. Thus assembled, such a container would now be a ‘dosimeter container’ that can be included in a larger batch sterilization process, disassembled after the process to extract the dosimeter film, and have that dosimeter film measured to discern the dose delivered to that container. Using such a technique, routine process measurements can be made and validations can be carried out to ensure that the desired SAL will be achieved.

As illustrated in FIGS. 5-7B, the container assembly 14 can be at least partially disposed in a receptacle 112 of a housing 110 of a shielding member that acts as a nest to shield certain aspects of the container assembly 14 from the sterilizing beam 106. The housing 110 may include one or a plurality of receptacles 112 to accommodate one or a plurality of container assemblies 14. The housing 110 may be constructed of any number of materials generally having a low atomic number (i.e., low-Z number). For example, the housing 110 may be constructed from aluminum, ceramics such as boron nitride, polymers such as polyethylene, ABS, polystyrene, or other polymers. Such materials can advantageously minimize production of x-rays created through Bremsstrahlung irradiation that may penetrate further than the electrons and thus discolor or otherwise impact the container assembly 14.

As shown in FIGS. 5 and 6, the housing 110 in the depicted version is bifurcated into a first shielding portion 111 and a second shielding portion 113 separated by an interface 115, which may be a physical or virtual interface depending on the specific construct of the housing 110, as will be discussed more below. The first shielding portion 111 includes a first surface 111 a, a second surface 111 b opposite the first surface 111 a, and a first bore portion 112 a extending therebetween. The first bore portion 112 a defines an opening 117 in the first surface 111 a of the first shielding portion 111. The second shielding portion 113 has a first surface 113 a, a second surface 113 b opposite the first surface 113 a, and a second bore portion 112 b extending therebetween. The first surface 113 a of the second shielding portion 113 is adjacent to the second surface 111 b of the first shielding portion 111 at the interface 115. So configured, the first and second bore portions 112 a, 112 b are aligned with each other to define the complete receptacle 112. It should be appreciated that while FIGS. 5 and 6 depict housings 110 with only a single receptacle 112, other versions of the shielding member includes a plurality of receptacles 112, each formed by complementary first and second bore portions 112 a, 112 b.

In some examples, the second bore portion 112 b of the second shielding portion 113 may extend completely between the first and second surfaces 113 a, 113 b, thereby forming a bore that extends completely through the second shielding portion 113. But in other examples, the second bore portion 112 b may only extend partly through the second shielding portion 113, i.e., through the first surface 113 a and into the second shielding portion 113 but short of the second surface 113 b, thereby defining a blind bore or cup-shaped recess.

The first shielding portion 111 and the second shielding portion 113 cooperate to define a number of blocking regions 114 positioned near the container 15 and container assembly 14 to restrict the sterilizing beam 106 from producing incidental, off-axis, angular, and/or reflected beams which may otherwise pass through the receptacle 112 and become incident on the container assembly 14. For example, the housing 110 may include a first blocking region 114 a positioned near the distal end 37 of the container assembly 14. In the illustrated example, the first blocking region 114 a may include a step portion 116 to accommodate the shoulder 76 of the container 15, thereby allowing the container 15 to nest within the receptacle 112 and be properly located within the housing 110. In other words, the receptacle 112 may include portions having varying diameters to accommodate specific dimensions of the container 15. In the depicted version, for example, the first bore portion 112 a of the receptacle has a diameter that is smaller than a diameter of the second bore portion 112 b. In other versions, the first and second bore portions 112 a, 112 b can have the same diameters.

In some examples, the second end 38 of the container assembly 14 is exposed through the opening 117 in the housing 110 during the sterilization process, as depicted in FIG. 5. This configuration ensures that the sterilization beam 106 is incident on the second end 38 of the container assembly 14 to provide the intended sterilization of the sealing interface 72 a and/or other components. Further, during the sterilization process, the first blocking region 114 a may retard or otherwise restrict irradiation from progressing towards the first end 36 of the container 15 a distance beyond the shoulder 76. That is, the step portion 116 may restrict or shield axial propagation (i.e., in a direction that is generally parallel to axis A) of the sterilizing beam 106.

The housing 110 may further include a second blocking region 114 b positioned near the elongated portion 38 of the container 15. The second blocking region 114 b protects the wall 38 of the container 15 and the drug 32 from unwanted exposure to the sterilizing beam 106. In some examples, the first shielding portion 111 and the second shielding portion 113 are integrally formed, and in some examples, the first shielding portion 111 and the second shielding portion 113 are distinct parts separated at the interface 115, for example, and stacked together without coupling, or they may be coupled together via any number of suitable approaches such as, for example, hinges, fasteners, and/or clasping devices. Additionally, the first shielding portion 111 and second shielding portion 113 may each themselves be made of multiple components that may be stacked or joined together.

In some forms, the blocking regions 114 may restrict propagation of the sterilizing beam 106 in any direction (i.e., in both a direction that is generally parallel to axis A and a direction that is non-orthogonal to axis A). Specifically, the blocking regions 114 a, 114 b may restrict the propagation of any sterilizing beams 106 that come into contact with the housing 110 in any direction. As a result, the sterilizing beam 106 may only be permitted to propagate through the container assembly 14, and any portions of the beam reflected, both directly and indirectly, into the housing 110 will be absorbed and not reflected. The housing 110 is sufficiently thick and has sufficiently spaced holes 112 to absorb the sterilizing beams 106.

By predetermining the energy of the sterilizing beam 106, the sterilizing beam 106 will only have sufficient energy to advance to a depth that is generally near the shoulder 76 of the container 15. Accordingly, the sterilizing beam 106 will make contact with any or all of the seal member 40, the coupling device 91, the overmold member 62, the clip member 53, and the sealing interface 72 a (formed by the seal member contact region 74 and the container contact region 72). In one embodiment, the sterilizing beam 106 may have a dose of approximately 25kGy at the sealing interface 72 a.

The container assembly 14, the housing 110, and the electron beam generator 105 may have any number of configurations. For example, as illustrated in the alternative embodiment presented in FIG. 6, the shoulder 76 may be pronounced due to the use of a flange 70 that is substantially narrower than the remainder of the container 15. In this embodiment, the housing 110 includes a first receptacle 112 a having a first diameter and a second receptacle 112 b having a second diameter that is substantially greater than the first diameter. However, in some embodiments (not shown), the receptacle 112 may have a constant diameter throughout its entire length.

In still other embodiments, the housing can be constructed to have a side-shielding portion. For example, FIGS. 8 and 9 depict one alternative housing 210 used in conjunction with a storage tub 201 for containing a plurality of container assemblies 14. The housing 210 in the depicted version includes a pair of stacked plates 203 a, 203 b, but could include a single plate or more than a pair of plates. The housing 210 includes a first shielding portion 211 and a second shielding portion 213. The first shielding portion 211 includes generally flat plate portion with a first surface 211 a, a second surface 211 b opposite the first surface 211 a, and a plurality of bores 212 a extending therebetween. Each bore 212 a defines an opening 217 in the first surface 211 a of the first shielding portion 211. The second shielding portion 213 extends from a perimeter of the first shielding portion 211 downward at an angle α relative to horizontal. So configured, the second shielding portion 213 acts as a side-shielding member when the assembly is loaded into the tub 201 as shown in FIG. 9. Specifically, as shown, a plurality of container assemblies 14 can be loaded in to the tub 201 in the upright standing orientation. Subsequently, the housing 201 can be placed into the tub 201 such that the plurality of bores 212 a receive the container assemblies 14 thereby aligning the first shielding portion 211 above the container assemblies 14 to protect the container assemblies 14 from downward projected sterilizing radiation. Additionally, as can be seen in FIG. 9, a distal end 215 of the second shielding portion 213 engages and rests upon a shelf surface 203 of the tub 201, which supports the housing 210 in the tub 201 and maintains the alignment of the housing 210 relative to the container assemblies 14. Moreover, as mentioned, the second shielding portion 213 serves as a side shielding member to prevent radiation that may other reflect inside of the tub 201 and impinge upon the container assemblies 14 from the perimeter region of the tub 201.

FIGS. 10 and 11 show another alternative embodiment of a housing 310 similar to that of FIGS. 8 and 9. In FIGS. 10 and 11, housing 310 is also used in conjunction with a storage tub 301 for containing a plurality of container assemblies 14. The housing 310 in the depicted version includes a single piece construction, but could include multiple pieces. The housing 310 includes a first shielding portion 311 and a second shielding portion 313. The first shielding portion 311 includes generally flat plate portion with a first surface 311 a, a second surface 311 b opposite the first surface 311 a, and a plurality of bores 312 a extending therebetween. Each bore 312 a defines an opening 317 in the first surface 311 a of the first shielding portion 311. The second shielding portion 313 extends from a perimeter of the first shielding portion 311 downward. So configured, the second shielding portion 313 acts as a side-shielding member when the assembly is loaded into the tub 301 as shown in FIG. 11. Specifically, as shown, a plurality of container assemblies 14 can be loaded in to the tub 301 in the upright standing orientation. Subsequently, the housing 301 can be placed into the tub 301 such that the plurality of bores 312 a receive the container assemblies 14 thereby aligning the first shielding portion 311 above the container assemblies 14 to protect the container assemblies 14 from downward projected sterilizing radiation. Additionally, as can be seen in FIG. 11, a distal end 315 of the second shielding portion 313 engages and rests upon a shelf surface 303 of the tub 301, which supports the housing 310 in the tub 301 and maintains the alignment of the housing 310 relative to the container assemblies 14. Moreover, as mentioned, the second shielding portion 313 serves as a side shielding member to prevent radiation that may other reflect inside of the tub 301 and impinge upon the container assemblies 14 from the perimeter region of the tub 301. Unlike the housing in FIGS. 8 and 9, the second shielding portion 313 of the housing 310 in FIGS. 10 and 11 extends generally perpendicularly downward from horizontal and stands on the shelf surface 303 of the tub 301. But in other versions, the second shielding portion 313 could extend at an angle relative to horizontal. Another distinction is that the housing 301 in FIGS. 10 and 11 includes added side shielding protection for the individual container assemblies. That is, as can be seen in FIGS. 10 and 11, the housing 310 includes a plurality of cylindrical collars 319 a and 319 b extending down from the second surface 311 b of the first shielding portion 311 for receiving the container assemblies 14. Interior surfaces 323 of the collards 319 can be contoured to closely fit and receive the container assemblies 14. Collars 319 a are located around the perimeter of the housing 310, and collars 319 b are located interior. The perimeter collars 319 a are longer and cover more of the respective container assemblies 14. That is, distal ends 321 of the perimeter collars 319 a can engage and rest upon the shelf surface 303 of the tub 301 same as the distal ends 315 of the second shielding portion 313. So configured, the collars 319 provide an extra added layer of protection against the possibility of radiation penetrating the housing 310 from the side perimeter of the tub 301 or otherwise.

Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept. For example, the container assembly 14 of the foregoing description and claims tends to resemble a cartridge for use in drug delivery devices, the disclosure is not limited in this regard. In other versions, the container assembly 14 can include a conventional vial or syringe barrel, for example, as such containers would also benefit from the teachings presented. Additionally, the means of sterilizing radiation may be selected to be principally from photons (i.e. x-rays) rather than electrons or some combination of photons and electrons. In this case, the generator 105 may be oriented similarly but have other means of generating ionizing radiation. An x-ray source may come from an electron-beam generator, or by other means. In the case where the ionizing radiation is principally x-rays, the appropriate photon (x-ray) energy level ranges will be different than those described for electrons, since photons will penetrate further through materials than electrons of the same energy level. Based on desired dimensions of the particular container assembly 14, x-ray beams may be used having any energy level between approximately 3 keV and approximately 50 keV, or any energy level between approximately 5 keV and approximately 25 keV, or any energy level between approximately 8 keV and approximately 20 keV.
